Prohibits cities and counties within the Portland MSA from enforcing requirements that developers provide affordable units in multiunit dwellings unless the city or county first calculates the developers' average expected losses due to providing affordable housing and the city or county offsets those losses.
SB 1521 revises Oregon law governing local affordable housing requirements, primarily for cities and counties in the Portland metropolitan statistical area (Portland MSA), and also updates related statutes affecting Metro, construction tax revenue use, publicly supported housing, and certain prior housing pilot programs. The bill authorizes local governments to require new multiunit housing to include affordable units or be sold/rented at regulated prices, but only if the local government also offers developers an option to pay an in-lieu fee and, in the Portland MSA for rental housing, provides offsets that are intended to match the expected marginal loss in value caused by the requirement.
The bill defines “affordable housing,” “multiunit housing,” and “Portland MSA,” and limits the new authority to larger developments: generally 20 or more units, or 10 or more units within the Portland MSA outside the City of Portland. It also exempts certain continuing care retirement communities and preserves protections for projects already far enough along in the permitting process before a new rule takes effect. Local governments may still offer voluntary incentives such as density bonuses, expedited permitting, fee reductions, tax exemptions, and other site-specific modifications to encourage more affordable units or lower prices.
A major feature of the bill is its requirement that, in the Portland MSA, any rental-housing affordability mandate must be backed by an economic analysis adopted by ordinance within the prior six years. That analysis must estimate the average expected marginal loss in value for a prototypical project, and the local government must offer offsets such as cash payments, property tax exemptions, or fee waivers/reductions at least equal to that loss. The bill gives local governments substantial discretion in how they conduct the analysis, states that individualized project-by-project analyses are not required, and limits appeals of the analysis and related decisions.
SB 1521 also amends Metro’s authority by removing and replacing prior restrictions on local inclusionary housing rules, and it revises the use of construction tax revenues so that a portion can fund developer incentives or offsets, down payment assistance, and other affordable housing programs. Additional sections update rules for publicly supported housing, the Stevens Road planning amendments, and residential design standards, including narrowing when local design standards can be applied to housing development within urban growth boundaries.
The overall sentiment reflected in the votes suggests the bill was supported by a majority but remained somewhat divisive. It passed the Senate 21-6 and the House 30-20, indicating meaningful bipartisan or cross-faction support alongside notable opposition. The main point of contention appears to be the balance between local affordable housing mandates and developer costs: supporters likely viewed the bill as a way to preserve or expand inclusionary housing tools while requiring compensation for economic impacts, while opponents likely objected to the added procedural burdens, limits on local authority, and the requirement to offset developer losses before enforcing affordability mandates.
The bill changes Oregon land use and housing law by creating a new framework under ORS chapter 197A that allows cities and counties to impose inclusionary housing requirements on new multiunit housing, subject to size thresholds, in-lieu fee options, and, in the Portland MSA, mandatory economic-analysis and offset requirements for rental housing. It also amends Metro’s housing authority, construction tax revenue allocation rules in ORS 320.195, and definitions and exclusions in the publicly supported housing statutes in ORS 456.766. Several prior special housing and planning provisions are also updated, including the Stevens Road and pilot project site statutes and a 2025 law limiting residential design standards, with operative dates staged mainly for January 1, 2028, and January 1, 2029.
The bill appears to have been viewed as a compromise between affordable housing advocates, local governments, and development interests: it preserves local authority to require affordable units, but conditions that authority on economic justification and developer offsets, especially in the Portland MSA. The recorded votes show clear support in both chambers but not overwhelming consensus, suggesting the measure was broadly viable yet still controversial. The absence of committee transcript excerpts limits direct insight into debate, but the structure of the bill indicates an effort to balance housing affordability goals with concerns about project feasibility and regulatory burden.
The central controversy is whether cities and counties should be allowed to require affordable units in new multiunit housing without first quantifying and offsetting the financial impact on developers. Supporters of stronger local affordable housing mandates would likely favor the bill’s authorization of inclusionary zoning tools, while opponents or skeptics of such mandates would likely focus on the required economic analysis, in-lieu fee structure, and mandatory offsets as necessary protections against reduced project viability. Additional points of contention include the bill’s special treatment of the Portland MSA, the limits on applicability to larger developments, the restrictions on appeals, and the reduction of local discretion through clear statutory formulas and timing rules.
